How do inflatable outdoor hot tubs for 4 people differ?

There are many criteria we can list here:

  • The shape (round or square?)
  • The size (what are the model’s dimensions?)
  • The appearance
  • The price
  • The features and
  • number of massage jets (Does it have only air jets or water jets as well?)
  • The extras (Does it have app control, LED lights, or other special features?)

In addition, there are a number of criteria that apply to virtually all models we mention and list here on our comparison portal:

  • Models are officially tested and approved by TÜV, meaning they meet safety standards
  • The models are winter-ready and can therefore be used year-round
  • The models can be quickly inflated without any prior knowledge, using the instructions and following just a few simple steps

What You Should Know About Outdoor Inflatable Hot Tubs for 4 People

First, here’s one of the most important tips we can give you: If the product description for an inflatable hot tub says “for 4 people,” that doesn’t mean all four people will have plenty of legroom while soaking in it.

In our experience, these hot tubs tend to be on the small side. That means: If you really want to use your new hot tub with four people frequently, you’re better off buying a larger model that’s rated for 5 to 6 people according to the description. (Note: There’s also an article on our website about inflatable hot tubs for 6 people.)  

With a larger model, you’ll ensure that you can all stretch out your legs without worrying about getting in each other’s way in the water.

However, if you plan to use the hot tub mostly as a couple and only occasionally with four people, a model advertised for 4 people is perfectly fine. 

How much free space do you have in your garden for the hot tub?

The same applies if you don’t have much free space left in your garden or on your patio. In that case, it may make sense—or even be necessary—to buy a smaller model. 

Our tip is therefore: Measure in advance the area you’re willing to “sacrifice” in your garden for your new outdoor hot tub, and then see which of the products you’re considering have the appropriate dimensions (length x width). 

How expensive or affordable should the hot tub for 4 people be?

Another question you should ask yourself and answer before making a purchase is regarding your budget.

As a general rule, portable inflatable hot tubs are, across the board, significantly cheaper than traditional outdoor hot tubs that are permanently installed in the garden. 

However, there are also price differences among the portable, air-filled models, as our comprehensive comparison and inflatable hot tub test have shown: Prices can range from around 350 to 1,500 euros. 

Our recommendation: Assess your budget, and then see what you can get with the money you have available. In our selection of outdoor hot tubs for 4 people, we’ve made sure there’s something for every budget.
